I concur that the description was more interesting than the video, nevertheless it works as a package. So I give it 4/5.
As for the discussion; I think it comes to various personal and circumstantial factors. Logically if the machine 'virtual' life = 'authentic' life, then you would incur a traveling for moving between realities (as, there is no such thing as 'free' movement). Therefore to minimize energy wastage, you may as well stay in this 'authentic' reality. Otherwise, if you were stuck in the 'virtual' reality, you would still incur a cost to move. Therefore, economically moving is not advisable in that case.
Philosophically - we are emotionally attached to that which we hold dear as reality and comfort; you will feel familiar with those who understand your experiences, places of living etc. So you must sacrifice familiarity to move to a new 'better' version with different sources of 'comfort'. It is a risk, and as humans we would be suspicious of such promises - so in reality we may stay here on earth.
That's that! Thanks for the great post and work. Keep thinking ^^ . . .
